I've noticed that after importing of a pkcs12 certificate YaCy erases pkcs12ImportFile and keyStorePassword parameters. I can understand that the former is erased to avoid reimporting the certificate again, however erasing of the latter prevents yacy to read the keystore.

Perhaps it was meant to erase pkcs12ImportFile and pkcs12ImportPwd parameters, not pkcs12ImportFile and keyStorePassword.

Steps To Reproduce

1. Set keyStore parameter with a location of a not-yet-existent file
2. Set keyStorePassword parameter with a new password
3. Set pkcs12ImportFile and pkcs12ImportPwd parameters to match certificate to import
4. Restart Yacy. Now you've got HTTPS on port 8443.
5. Restart Yacy again. Now you don't.
